Hi Rick,

I'm looking forward to the release of the PIN daemon functionality.

In our case (dot IE ccTLD), we would like to be able to have two nodes access our DB and HA HSMs.

Every time we need to generate and sign a zone, we generate a zone with a serial of, for example, 2012080801 on nodeA and 2012081501 on nodeB. All other data within the unsigned zones is identical apart from the serial.

Each of those unsigned zones is then signed and validated etc.

We use this approach so that we can publish a last-known good zone, with up to one week's grace, should some disaster happen where a bad signed zone was published (for whatever reason).
